🌌 Did you know every atom is like a mini solar system: a nucleus packed with positively charged protons ( ) and neutral neutrons (0) at the center, surrounded by speedy negatively charged electrons (-) buzzing in energy-level shells? ���📊 Atomic Number = Number of protons (like Carbon's 6!) which defines the element. Mass Number = Protons Neutrons (e.g., Carbon-12). Electrons fill shells: 2 in the first, up to 8 in the second, powering chemical reactions in our everyday world! ���Perfect STEM
